BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a shower pipe.

Description of the Prior Art

The conventional shower device is provided with a flower higher than thehead of a user, which can directly wash the shoulder and neck of thebody. However, it is necessary to adjust the flower according to variousheights of users.

The conventional shower device includes a telescopic tube, a bushing anda threaded rod. The telescopic tube includes an upper tube and a lowertube, and the bushing is disposed on the upper tube and is locatedbetween the upper tube and the lower tube. The threaded rod is insertedwithin and locks the lower tube to urge and radially deformed thebushing to tighten the upper tube to positioningly secure the upper andlower tubes. However, the conventional telescopic tube is positionedonly by the threaded rod in single-point positioning. It has thedisadvantage of poor positioning effect such that the threaded rod andthe bushing are often unable to resist the impact of the strong waterflow, resulting in the upper tube being easy to loosen relative to thelower tube. As a result, it is difficult to stabilize and fix the flowerat a specific height required for a user.

The present invention is, therefore, arisen to obviate or at leastmitigate the above-mentioned disadvantages.
